Fatal error during KafkaServer startup. Prepare to shutdown
kafka.common.InconsistentBrokerIdException: Configured broker.id 56
doesn’t match stored broker.id 103 in meta.properties
解决办法：
找到问题主机（我的是data1主机kafak出现问题），配置文件
[root@data1 ~]# find / -name server.properties find: ‘/proc/16934’: No such file or directory /usr/hdp/3.1.0.0-78/etc/kafka/conf.default/server.properties /opt/cloudera/parcels/CDH-6.2.1-1.cdh6.2.1.p0.1425774/etc/kafka/conf.dist/server.properties [root@data1 ~]# cat /usr/hdp/3.1.0.0-78/etc/kafka/conf.default/server.properties |grep log.dirs log.dirs=/tmp/kafka-logs
修改brokerid,与图中一致即可
[root@data1 ~]# find / -name meta.properties /var/local/kafka/data/meta.properties [root@data1 ~]# vi /var/local/kafka/data/meta.properties # #Sun Jul 25 00:38:56 CST 2021 version=0 broker.id=56问题二
解决CDH中启动hdfs，报错 Canary 测试无法在目录
/tmp/.cloudera_health_monitoring_canary_files 中创建文件
解决方法：
[root@master ~]# sudo -uhdfs hdfs dfsadmin -safemode leave
待续。。。
